This is the only adapter available for my car to use factory amps and steering wheel controls. The products but not very easy to use and figure out. It works well overall, but you will lose your phone steering wheel options, volume and stuff still works. Unfortunately there are no other cheaper options, but if you want to go aftermarket, this is what you need. I later installed after market, so I really only needed the steering wheel control module, but oh well, live and learn.
